Problems solved by technology

[0003] According to different uses, the function of the adhesive is also significantly different. The temperature difference between day and night, summer and winter of the high-grade pavement surface layer is very large. After a period of use, the flexibility of the adhesive used for the pavement coating will be greatly reduced. The overall functionality of pavement pavement is reduced, which in turn affects its service life
At the same time, the changing climate and environment will also affect the service life of the adhesive

Abstract

The invention relates to a modified epoxy thin-layer adhesive used for a bridge road surface. The modified epoxy thin-layer adhesive comprises a component A and a component B, wherein the component A is prepared from modified epoxy resin, butadiene-styrene copolymerization resin, 3,3-dichloride biphenyl 4,4-diisocyanate, a filler, a diluent and a plasticizer; the component B is prepared from hydrogen-containing polysiloxane, a catalyst, a curing agent, an accelerant and a defoamer; the mass ratio of the component A to the component B is 1:(0.5-1.8). The epoxy resin double-ingredient thin-layer adhesive belongs to special adhesive, is used for the bridge pavement, has the advantages of high intensity, friction resistance, high weather fastness, convenience in construction, high curing speed, high integral strength after gel forming, small possibility of tearing and no suncrack, and is more flexible since the adhesive has rubber elasticity.

Description

technical field [0001] The invention relates to an adhesive for bridge pavement and a preparation process thereof, and belongs to the technical field of two-component high molecular polymer adhesives. Background technique [0002] Epoxy resin adhesives have made rapid progress in the performance, variety and application of adhesives. Epoxy resin and its curing system have also become an important class of adhesives with excellent performance, many varieties and wide adaptability due to their unique and excellent performance and the continuous emergence of new epoxy resins, new curing agents and additives. Epoxy resin adhesive is composed of epoxy resin, curing agent, plasticizer, accelerator, diluent, filler, coupling agent, flame retardant, stabilizer and so on. Among them, epoxy resin, curing agent, and toughening agent are indispensable components, and others can be added or not according to needs. [0003] According to different uses, the function of the adhesive is al...
